We show that the cobordism maps on Khovanov homology can distinguish smooth surfaces in the 4-ball that are exotically knotted (ie, isotopic through ambient homeomorphisms but …
Following the seminal articles of Jones, Witten and Atiyah [38; 86; 3], Crane and Frenkel outlined their vision for an algebraic construction of invariants of smooth 4–dimensional …

We interpret Manolescu–Neithalath's cabled Khovanov homology formula for computing Morrison–Walker–Wedrich's KhR2 skein lasagna module as a homotopy colimit (mapping …
We construct a Kirby color in the setting of Khovanov homology: an ind-object of the annular Bar-Natan category that is equipped with a natural handle slide isomorphism. Using …

The Hecke algebras for all symmetric groups taken together form a braided monoidal category that controls all quantum link invariants of type A and, by extension, the standard …
We show that the Khovanov-Rozansky $\mathfrak {gl} _2 $ skein lasagna module distinguishes the exotic pair of knot traces $ X_ {-1}(-5_2) $ and $ X_ {-1}(P (3,-3,-8)) $, an …

We construct analogs of Khovanov-Jacobsson classes and the Rasmussen invariant for links in the boundary of any smooth oriented 4-manifold. The main tools are skein lasagna …
To every compact oriented surface that is composed entirely out of 2-dimensional 0-and 1- handles, we construct a dg category using structures arising in Khovanov homology. These …

These are expository lecture notes from a graduate topics course taught by the author on Khovanov homology and related invariants. Major topics include the Jones polynomial …
